Explain the causes of Global Warming.

Global warming is the long-term warming of the planet Earth. It is caused by an increase in the average temperature of the Earth's atmosphere, especially in the lower atmosphere (troposphere), which can contribute to changes in global climate patterns.

There are several main causes of global warming:

Greenhouse gases: These gases, such as carbon dioxide (CO2), methane, and water vapor, trap heat in the Earth's atmosphere, making it warmer. The main human activity that contributes to the increase in greenhouse gases is the burning of fossil fuels (such as coal, oil, and gas) for energy, transportation, and industrial processes. Deforestation and land use changes also contribute to the increase in greenhouse gases, as trees and other vegetation absorb CO2 and help to regulate the Earth's temperature.

Solar radiation: The sun is the main source of energy for the Earth, and its radiation drives the Earth's climate system. Changes in the sun's intensity or the Earth's orbit can affect the amount of solar radiation that reaches the Earth's surface and contribute to global warming.

Volcanic eruptions: Large volcanic eruptions can release large amounts of gases and particles into the atmosphere, which can have a cooling effect on the Earth's surface. However, the overall effect of volcanic eruptions on global warming is small compared to the effect of human activities.

Other natural factors: There are other natural factors that can contribute to global warming, such as changes in ocean currents and the El Niño-Southern Oscillation (ENSO) cycle. However, these factors do not explain the rapid increase in global temperatures that has occurred in recent decades, which is largely due to human activities.

Overall, the main cause of global warming is the increase in greenhouse gases in the Earth's atmosphere, which is largely caused by human activities such as the burning of fossil fuels and deforestation. The resulting increase in the Earth's average temperature is leading to significant changes in global climate patterns and is having a range of negative impacts on the planet, including rising sea levels, more frequent and severe weather events, and the loss of biodiversity.
